User: Three charges, Q1, Q2, and Q3 are located in a straight line. The position of Q2 is 0.323 m to the right of Q1. Q3 is located 0.136 m to the right of Q2. The force on Q2 due to its interaction with Q3 is directed to the (Give ALL correct answers, i.e., B, AC, BCD...) A) right if the two charges are negative. B) left if the two charges are positive. C) left if the two charges have opposite signs. D) left if the two charges are negative. E) right if the two charges have opposite signs.

Suppose you pour water into a container until it reaches a depth of 36.7 cm. Next, you carefully pour in a 10.4 cm thickness of olive oil so that it floats on top of the water. What is the pressure at the bottom of the container? Assume 1000 kg/m3 and 940 kg/m3 for the density of water and the oil, respectively.

Solution:

Formula:

P = Dgh

Where P = Pressure, D is the Density, g = gravity and h = Depth

First we will calculate the pressure due to the oil and this pressure is termed as P1. Similarly, the Density of oil is D1 and Depth of oil is h1.


D1 = 940 kg/m3
h1 = 10.4 cm
g = 9.81 m/s2

P1 = D1*g*h1 = 940 * 9.81 * 10.4 = 95902.56 N/m^2

Now, we will calculate the pressure due to the oil and this pressure is termed as P2. Similarly, the Density of oil is D2 and Depth of oil is h2.

D2= 1000 kg/m3
g = 9.81 m/s2
h2 = 36.7 cm

P2 = D2*g*h2 = 1000 * 9.81 * 36.7 = 360027 N/m^2

The pressure at the bottom of the container is the total pressure = P1 + P2

Thus, P = P1 + P2
= 455929.56 N/m^2

When a glass rod is rubbed with a piece of silk it acquires a positive charge and the silk acquires a negative charge. This process signifies that A) the glass rod gained electrons from the piece of silk B) the glass rod lost protons to the piece of silk C) the glass rod gained protons from a piece of silk D) the glass rod lost electrons to the piece of silk
Weegy: D) the glass rod lost electrons to the piece of silk An atom has equal amounts of protons(+) and electrons(-). [ When an atom loses an electron which is (-) charged, the atom has more protons than electritrons, so the atoms electrical charge becomes positive ] User: Electrical and gravitational forces follow similar equations with one main difference: A) gravitational forces obey the inverse square law and electrical forces do not. B) electrical forces obey the inverse square law and gravitational forces do not. C) gravitational forces are always attractive but electrical forces can be attractive or repulsive. D) electrical forces attract and gravitational forces repel. Weegy: C) gravitational forces are always attractive but electrical forces can be attractive or repulsive. (More)
